摘要：

Asthma is a chronic allergic ailment affecting a considerably large population of the world. The aim of this study is to evaluate the ameliorative effects of vanillic acid against ovalbumin (OVA)-induced asthma in rat model. Asthma was induced in Sprague Dawley rats and vanillic acid was orally administered at 25 and 50 mg/kg body weight for 28 days. Rats challenged with OVA showed heavy signs of airway inflammation and remodeling similar to chronic asthma, evidenced by the increased differential cell counts and presence of inflammatory cytokines in the bronchoalveolar lavage fluid (BALF), along with elevated serum immunoglobulin levels, and the histological results. However, vanillic acid dose-dependently attenuated the manifestation of OVA-induced asthma (p < 0.05) through suppression of inflammatory mediators and modulation of immunoglobulin levels in rats. The asthma mitigating properties of vanillic acid might be due to suppression of oxidative stress and prevention of lung airway inflammation.
